Vega 100G and Vega 200G Gamma Config Guide This document aims to go through the steps necessary to configure the Vega 100G and 200G gateways to be used with a Gamma SIP Trunk. When a SIP trunk is provisioned by Gamma a list of information will be provided an example list is show below: - The Public IP that the SIP trunk communicates with - DDIs allocated to the Trunk - Gamma SIP Trunk Source - 88.215.61.201 Gamma SIP Trunk ISDN to PBX VEGA 100G or VEGA 200G To help make this example guide more complete we will use some example network configuration: The Example Gamma Trunk Telephone number 01258 159826 The example installation public IP - 212.36.44.14 The default gateway IP for LAN 192.168.1.1 The Vega gateway LAN IP address - 192.168.1.100 NOTES: Gamma SIP Trunks are normally IP Authenticated, this means that SIP Registration is not used. The Gamma VoIP servers are located at 88.215.61.201 (SIP) and 88.215.61.202 (Media), if the installation environment is behind a NAT both of these IP address will need to be port forwarded in the router to the internal Vega IP Address. The setup procedure that follows will focus on the configuration of the Vega for basic operation behind a NAT, Configuration of the Vega to operate against the Gamma SIP Trunk and a section for configuring the Vega to work with a generic E1 PBX.
STEP 1: Log into the Vega gateway using the WebUI interface. The default user is admin and password is admin. STEP 2: As the Vega gateway WebUI loads up the Status page as shown below. Once the page has finished select the "Quick Config" menu option as shown below: STEP 3: The WebUI will present a warning message please read the message and then select "Continue" on the screen below.
STEP 4: Once the Quick Config UI has loaded select the "Basic" Tab. This is where the Country localization, IP address and Ethernet configuration is entered. To setup for Gamma only IP Address changes should need to be made LAN 1 Configuration The default setting is for LAN to be configured by a DHCP server To setup a Static LAN configuration untick the RED highlighted tickbox and fill out the IP address Table config (the IP Address parameters become editable after disabling DHCP). Country - Changing the country configuration may require the current changes to be re-submitted to the Vega and may result in the Topology being changed from E1 to T1. The standard setting is UK which should not need to be changed NOTE You must specify the correct country for the Vega to use the correct PRI topology(e1 or T1) and for the correct network tones to be configured. NOTE - CHANGES TO THE VEGA IP ADDRESS WILL REQUIRE A REBOOT TO BECOME OPERATIONAL
STEP 5: VoIP Configuration Once the Basic config is completed select the "VoIP" tab. The screen shot below highlights the most important fields. NOTE This STEP covers the basic VoIP configuration for Gamma there an additional SIP setting that must be set, this is covered in STEP 9 SIP Domain: This is should be configured as 88.215.61.201 SIP Server Address: This is should be configured as 88.215.61.201 This is the Gamma SIP IP Address that the will communicate with. Outbound Proxy address: Not used Registration mode: Must be set to OFF (off is default) Registration and Authentication ID: When Registration Mode is set Off these parameters are greyed out This is not used with the Gamma SIP Trunk. Authentication Password: This is not used with the Gamma Trunk.
STEP 6: E1 Configuration Once the VoIP config is competed select the "T1 or E1" tab. A screenshot below gives the example of an E1 tab. Telephone number list: This is configured as ".* " which is routing terminology for any telephone number character with any length of characters. The field defines which telephone numbers the Vega will route from SIP out to the E1/T1 trunk interfaces. The Telephone number list will need to be configured for EACH E1/T1 port that is being used, in most cases.* is all that needs to be configured for each E1. NT? : Tick box should be Ticked Defines whether each Vega E1 interface will emulate NT or TE modes. Normally the Vega will connect the Gamma SIP trunk to an ISDN PBX Each E1 that connects to the ISDN PBX will be emulating a Telco E1 and should be set to NT This field should be configured for EACH E1/T1 port that is being used (by default E1/T1 interface 2 is set for NT mode) Protocol: This defines E1 protocol being used. Which protocol is used will depend on what device the Vega E1is plugged into most European TDM PBXs will use ETSI. For E1 the following protocols are supported: ETSI (EURO ISDN), QSIG, VN, CAS-R2, CAS-PW, arinc, 1tr6 and Other E1 TAB Config Notes: All E1s or T1s present on the Vega will be enabled by deafult. Both Vega 100G and 200G support two E1 interfaces however a Vega 100G is provisioned for 30 VoIP channels and the Vega 200G supports 60 VoIP channels. The E1 interface pin out for Vega 100G and 200G is fixed and staggered: E1 interface #1 has the pin out for TE operation (to connect to a Telco E1) E1 interface #2 has the pin out for NT operation (to emulate a telco E1 and connect to PBX)
STEP 7: Confirm Settings changes The parameters to be configured by Quick config are complete - select the "Submit" button. NOTE The Quick Config Submit creates a popup Click "OK" on the next window to apply the settings. STEP 8: Quick Config Steps Complete Select the Continue to return back to the Vega Status page This concludes the Vega WebUI setup, there legacy PBX may require additional configuration depending on vendor specific requires, but for most E1 PBXs the configuration setup above will be sufficient to enable normal operation of the PBX with the Gamma SIP Trunk.
STEP 9: Expert Config SIP From header domain One of the requirements for setting up the Vega for the Gamma SIP Trunk is for the Vega to fill the SIP From header with the Vega public IP, to do this use the WebUI and Navigate to > Expert Config > SIP > SIP Profile (modify) Following the example configuration stated at the beginning of the document Local Domain: This is configured by Quick Config and should not be changed Alternative Local Domain: 212.36.44.14 This should be configured with the Public/ WAN of the Vega, the example config used for this guide is shown in the screen shot. From Header Host: Alt Local Domain This is the final SIP configuration that will need to be made. After the config changes have been made the changes will need to be submitted, the RED arrow indicates Submit to change the settings please note that an Apply and Save will still need to be carried out for the config change to become permanent.
STEP 10: Optional If behind NAT configure basic Vega NAT Traversal please follow this instruction step if not please got to the next step. If the Vega is not assigned a WAN IP address and is behind a NAT the Vega LAN NAT Profile will need to be configured, please navigate to > Expert Config > LAN/WAN > NAT configuration (NAT). From the NAT page please select Modify for the LAN 1 NAT Profiles table - The External IP will need to be configured with the Public/WAN IP for the Internet connection being used the guide example uses 212.36.44.14 After the config change has been added to the field this will need to be submitted, the RED arrow indicates Submit button to change the settings Please return to the NAT Page (> Expert Config > LAN/WAN > NAT configuration (NAT) ) Next the NAT Configuration will need to be Enabled via the LAN 1 NAT configuration Enable tickbox After the config change has been added to the field this will need to be submitted, the RED arrow indicates Submit button to change the settings
STEP 11: Optional PBX Trunk CLID replacement If the Gamma SIP Trunk CLID is different from the ISDN PBX Trunk ID and the PBX settings cannot be changed it is possible to change the CLID presented by the Vega gateway to match the ID for the Gamma SIP Trunk, to do this we would use the Vega Dial Plan to over write the outbound (To_SIP) CallerID. Navigate to >Expert Config > Dial Plan > To_SIP (modify) After selecting the To_SIP dial plan enter the following,telc:trunk_id_number (an example is show in Green below) After the config change has been added to the field this will need to be submitted, the RED arrow indicates Submit button to change the settings STEP 12 Apply and Save Changes in Expert Config must first be submitted using the Submit buttons for the different Web tables For the changes to be made to Running config the left side Apply button must selected, this button will be highlighted RED when this operation needs to be carried out. For the changes to be Saved back to flash the left side Save button must selected this button will be highlighted RED when this operation needs to be carried out. This is the last step for configuring the Vega Gateway for operation against a Gamma SIP Trunk
Appendix 1 Capturing Traces for Tech Support Analysis Below are a series of steps to run in order to capture vega debug information to send to Sangoma Tech support. Support information is made up of two parts a debug trace collection and a show support collection, both of these should be collected issues relating to Vega behavior. For config questions a show support would be sufficient to give the support engineer a background of how the Vega is currently configured All General capture trace scenarios STEP 1: Run the below series of commands in WebUI debug enable router rs debug enable _isdn 89 debug enable _logger i log display v sip monitor on log display off debug on a) Log into the webui http://<ip of Vega>/ (i.e. http://192.168.2.12/) b) Navigate to >Expert Config -> Advanced > Enter the commands from the grey text box <At this point please reproduce the issue that you are experiencing> After the issue behavior has concluded please enter the command debug dump to the CLI.
This will fill the popup window with the debug traces please copy all text "ctrl->a" (select all) and paste this into a txt file please name this file debugdump.txt Finally then type the command "show support" in the CLI Command window and select Submit. This will popup a new window with the output of the command. Copy all text "ctrl->a" (select all) and paste this into a txt file please name this file debugdump.txt With both of these files please navigate to http://support.sangoma.com and raise a ticket providing a description of the issue and the trace files a Sangoma Support engineer will then help you with your issue. Appendix 2 Below is an example of a Gamma provisioning Email IPDC Order Confirmation Email Your Order Details Order ID IPDC Endpoint Name Your CPE IP Address Channels Created 159xxx DC2N13QEO9xxx <your WAN IP Address> x DDIs Allocated to this endpoint 0149441xxxx 0149441xxxx 0149441xxxx 0149441xxxx Configuration - Ports & IP Traffic on the following ports must be forwarded through relevant routers and firewalls on the customer premises Signalling:UDP port 5060 egress/ingress to:- 88.215.61.201 Media: All UDP ports between 6000-40000 egress/ingress to:- 88.215.61.202
Configuration - SIP Headers The SIP headers originated from the CPE should be set as follows:- Request-URI Header The number within the Request-URI is used for routing calls and should contain the called number. The format of this number can either be UK national format (with leading zero) or full e.164 format (with leading +). Examples INVITE sip:+441618777148@100.100.100.29 SIP/2.0 INVITE sip:00441618777148@100.100.100.29 SIP/2.0 INVITE sip:01618777148@100.100.100.29 SIP/2.0 TO Header Header must contain IPDC SIP gateway address and the called number. The format of this number can either be UK national format (with leading zero) or full e.164 format (with leading +). Examples: To: <sip:+441618777148@100.100.100.29> To: <sip:00441618777148@100.100.100.29> To: <sip:01618777148@100.100.100.29> FROM Header The user part of the SIP URI within the 'From' header must contain the Calling Line Identity of the originating device. This identity must be a number registered to the endpoint. The format of this number can either be national significant (with or without a leading zero), or in full e.164 format. The domain part of the SIP URI within the 'From' header can contain either the IP address of the public facing interface or a customer-defined FQDN. Gamma will not use this FQDN for any purpose Examples From: <sip:+441618777148@100.100.100.29> or using FQDN From: <sip:+441618777148@your.domain.local> From: <sip:01618777148@100.100.100.29> or using FQDN From: <sip:01618777148@your.domain.local> From: <sip:1618777148@100.100.100.29> or using FQDN From: <sip:1618777148@your.domain.local> PAID Header The format of the PAID number can either be national significant (with or without a leading zero), or in full e.164 format. If no PAID header is provided, Gamma will insert a PAID header with the default network CLI. Examples P-Asserted-Identity: <sip:+441618777148@100.100.100.29> P-Asserted-Identity: <sip:01618777148@100.100.100.29> P-Asserted-Identity: <sip:1618777148@100.100.100.29> Important Notes Number Porting If you require to port numbers to the IP Direct Connect endpoint, this process can only commence once the new IP Direct Connect node has successfully been provisioned and tested. Quality of Service (QoS) For connections to IPDC via public internet, Gamma will not support or deliver marked voice traffic (Signalling or Media). For connection to IPDC via private interconnect, QoS markings will be agreed during the interconnect establishment stage. Service Acceptance Tests
